springBoot配置方式

1.通过手动配置文件的形式来进行配置

手动配置则是创建普通的java工程,然后再进行pom文件的属性添加如下的内容:

<parent>
          <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.1.8.RELEASE</version>
        </parent>
    
        <dependencies>
    
          <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
        </dependencies>

2.通过idea的自动生成的形式来进行配置

自动构建生成的pom文件如下图所示:

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
        <parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.7.4</version>
            <relativePath/> 
        </parent>
        <groupId>com.ydl</groupId>
        <artifactId>springBoot-init</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <name>springBoot-init</name>
        <description>springBoot-init</description>
        <properties>
            <java.version>17</java.version>
        </properties>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <optional>true</optional>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>
        </dependencies>
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <configuration>
                        <excludes>
                            <exclude>
                                <groupId>org.projectlombok</groupId>
                                <artifactId>lombok</artifactId>
                            </exclude>
                        </excludes>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    
    </project>

3.如果构建聚合项目,则idea自动生成的module的pom文件需要修改:

parent的组件如下:

<groupId>com.ydl</groupId>
    <artifactId>ydl-alibaba-cloud</artifactId>
    <version>0.0.1-SNAPSHOT</version>

自动生成的springboot的pom文件中的<parent>标签原始内容如下:

<parent>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-parent</artifactId>
         <version>2.7.4</version>
         <relativePath/> 
    </parent>

要修改为同父工程一致,修改后如下所示:

<parent>
         <groupId>com.ydl</groupId>
         <artifactId>ydl-alibaba-cloud</artifactId>
         <version>0.0.1-SNAPSHOT</version>
    </parent>

然后将子工程的

<groupId>以及<version>去掉

![237aa2c4d9bb4a529c1813c04a6d5d13.png][]

保持和父工程的一致

查看父工程和子工程的packaging方式,分别应为

否则会报错

Tag name: project Description : The <project> element is the root of the descriptor. 
    The following table lists all of the possible child elements. Version : 3.0.0+

而后将子工程的

<artifactId>nacos-provider-8000</artifactId>

添加到父工程中

<modules>
        <module>nacos-provider-8000</module>
    </modules>

4.如果在子工程中不想写导入的包的版本,需要在父工程中指定依赖如下

<dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>com.alibaba.cloud</groupId>
                    <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                    <version>2021.0.1.0</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
    
                <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-dependencies</artifactId>
                    <version>2021.0.1</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
        </dependencyManagement>
